Class RequestContext

java.lang.Object

org.springframework.web.servlet.support.RequestContext

Direct Known Subclasses:

JspAwareRequestContext

public class RequestContext
extends Object

Context holder for request-specific state, like current web application context, current locale, current theme, and potential binding errors. Provides easy access to localized messages and Errors instances.

Suitable for exposition to views, and usage within JSP's "useBean" tag, JSP scriptlets, JSTL EL, etc. Necessary for views that do not have access to the servlet request, like FreeMarker templates.

Can be instantiated manually, or automatically exposed to views as model attribute via AbstractView's "requestContextAttribute" property.

Will also work outside DispatcherServlet requests, accessing the root WebApplicationContext and using an appropriate fallback for the locale (the HttpServletRequest's primary locale).
